Problem with multiple images on a page

I'm new to PdfBox,

I'm having trouble adding multiple images on a PDPage

This is the method that adds images:
[...]
 private void addImage(PDDocument document, PDPage page, String
imageName, int x, int y) throws IOException {
        System.out.println("Image Name: " + imageName);

        PDXObjectImage image = new PDJpeg(document, new
FileInputStream(imageName));
        PDPageContentStream contentStream = new
PDPageContentStream(document, page, true, false);
        int oldWidth = 200;
        int oldHeight = 300;
        int newWidth = 150;
        int newHeight = (newWidth * oldHeight) / oldWidth;
        image.setHeight(newHeight);
        image.setWidth(newWidth);
        contentStream.drawImage(image, x, y);
        contentStream.close();
    }
[...]t

even if the image name changes only the first image is repeatedly drawn on page.

and If I move the line:
       PDXObjectImage image = new PDJpeg(document, new
FileInputStream(imageName));
after
       PDPageContentStream contentStream = new
PDPageContentStream(document, page, true, false);

the resulting page is blank.

thanks in advance,
Stefano
